+### How to Contribute
+
+We prefer to receive contributions in the form of GitHub pull requests. Please
+send pull requests against the [github.com/apache/arrow][4] repository.
+
+If you are looking for some ideas on what to contribute, check out the [JIRA
+issues][3] for the Apache Arrow project. Comment on the issue and/or contact
+[dev@arrow.apache.org](http://mail-archives.apache.org/mod_mbox/arrow-dev/)
+with your questions and ideas.
+
+If you\u2019d like to report a bug but don\u2019t have time to fix it, you can still post
+it on JIRA, or email the mailing list
+[dev@arrow.apache.org](http://mail-archives.apache.org/mod_mbox/arrow-dev/)
+
+To contribute a patch:
+
+1. Break your work into small, single-purpose patches if possible. It\u2019s much
+harder to merge in a large change with a lot of disjoint features.
+2. Create a JIRA for your patch on the [Arrow Project
+JIRA](https://issues.apache.org/jira/browse/ARROW).
+3. Submit the patch as a GitHub pull request against the master branch. For a
+tutorial, see the GitHub guides on forking a repo and sending a pull
+request. Prefix your pull request name with the JIRA name (ex:
+https://github.com/apache/arrow/pull/240).
+4. Make sure that your code passes the unit tests. You can find instructions
+how to run the unit tests for each Arrow component in its respective README
+file.
+5. Add new unit tests for your code.
+
+Thank you in advance for your contributions!
